Abstract : The Report documents the research and development effort of a program for the study of four microassembly connector designs. These connector designs are (1) Receptacle for the hermetic sealed Micro Circuit Module (MCM), (2) Encapsulated MCM header and receptacle - 36 contacts, (3) Encapsulated MCM header and receptacle - 80 contacts and (4) MCM Microwafer test socket. The development and evaluation of these four connector designs are documented in this report. Included are design drawings and a summary of the test results. A receptacle design for the twenty pin MCM was fabricated using production type tooling and was demonstrated to be suitable for Military equipments. A unique test socket for the testing of MCM Microwafers was also designed, fabricated and demonstrated to meet the full requirements of the program. Models of the 36 and 80 contact MCM header and receptacle connectors fabricated using production type tooling did not meet the specified requirements. The primary problem with these connectors was concluded to be the variation inherent in raw contact material and the difficulty to control fabrication of the minute contacts required for the application.
